2. Related Art
Typically, a lineman uses a ratchet strap and clamp to tension an electrical cable in order to replace or remove a dead-end insulator. This process involves applying a tensioning force to the electrical cable such that the dead-end insulator may be removed without accidentally letting the live powerline fall out of control of the lineman. In current systems, preventing this from occurring is achieved with a series of clamps and ratchet straps. The ratchet strap is connected to a utility pole and held fast while the clamp is attached to an electrical cable. The ratchet strap is then tightened to tension the electrical cable. These ratchet straps and clamps require skill to handle and often require more dexterity than two hands provide. In some cases, remotely operated equipment controlled by an operator may be elevated to the electrical cable instead of a lineman. The remotely operated equipment removes the lineman from the work area. However, existing ratchet systems are not suitable for use by remotely operated equipment. They possess the same lack of dexterity that linemen possess when using the ratchet straps and clamps to tension the electrical cable.
Embodiments solve the aforementioned problems by providing systems and methods for tensioning an electrical cable and maintaining tension on said electrical cable. Tensioners fixed to a rigid object may be configured to adjust the tension of a connecting line fixed to an electrical cable such that a length of the electrical cable between the rigid object and the clamp becomes slack while tension is maintained in another portion of the electrical cable such that one or more robotic appendages may remove, replace, repair, or conduct any alteration or modification to said slack electrical cable and the connection of the electrical cable to a rigid object (e.g., a utility pole or utility pole cross-arm) such as a dead-end insulator.
In some embodiments, the wire tensioning system comprises a mount, a tensioner, a connecting line, a clamp, and a supporting structure with suspension mediums. In some such embodiments, the wire tensioner is adapted to be hanged from an electrical cable by said suspension mediums. In the wire tensioning system, the tensioner interfaces with the connecting line and adjusts the tension thereof. The connecting line, fixed to the clamp, in turn tensions the electrical cable which allows the one or more robotic appendages remove, repair, replace, or perform any alteration or modification upon the electrical cable and a connection of the electrical cable to a rigid object (e.g., a utility pole or utility pole cross-arm) such as a dead-end insulator.

For example, the present disclosure may be utilized in a variety of applications, including but not limited to military applications, construction applications, rescue applications, health and safety applications or other applications that robotics may be utilized. Accordingly, it will be appreciated that specific embodiments or details provided herein are intended to be illustrative, rather than limiting.
As depicted in the block diagram 200, a remote robot assembly 202 comprises at least a remote capture device 210, a computer 260, and a control system 280. In some embodiments, and as described in greater detail herein, the remote capture device 210 may be a device configured and adapted for the capturing of sensory information and may be positioned on a robot unit for the capturing of sensory information that may be utilized by computer 260, to present information to an operator via control system, among other purposes.
Through selective inputs, including both manually inputted instructions and/or automated instructions, remote capture device 210 may capture video, still images, three-dimensional depth information, audio, electrical conductivity, voltage, among other information that may be captured by a sensor or recording device. For example, remote capture device 210 may comprise at least one camera 212 for the capturing of video or still images (collectively, “video”). The at least one camera 212 may be a camera positioned on remote capture device 210 for the capturing of video within a selected field of view. The resolution of the video captured by camera 212 may vary, but in some embodiments, camera 212 may be a camera configured for capturing in at least 720p resolution but may capture in higher resolution including but not limited to 1080p, 2K, 4K, or 8K resolution. However, it will be appreciated that the camera 212 may be any currently known or yet to be discovered camera for capturing video. Video captured from camera 212 may be stored locally at remote capture device at a local memory 214. The storing of video at local memory 214 may aid in providing a failsafe or backup storage of captured video in the event of a transmission or upload failure. Further, the storing of video at local memory 214 may aid in situations of poor wireless connection or if a direct line becomes loos or interrupted, preventing the immediate transmission of captured video. Optionally or additionally, video captured from camera 212 may be transmitted to computer 260 for processing, analyzing, storage, and/or for later transmitting to control system 280. In further embodiments, video captured from camera 212 may be directly transmitted to control system 280 for processing.
In some embodiments, remote capture device 210 may further comprise at least one three-dimensional camera 216 or other device configured for capturing three-dimensional depth information. As described in greater detail below, the three-dimensional depth camera 216 may be utilized for capturing three-dimensional depth information within a field of view for creating a point cloud, 3-D model, or other digital representation of an object or area scanned or viewed by the three-dimensional camera 216. Three-dimensional camera 216 may be operated in conjunction with, or independent from camera 212 or other components or parts of remote assembly 202 and/or remote capture device 210. As described in greater detail below, in response to instructions or an input, three-dimensional camera 216 may begin capturing three-dimensional depth information about an object or area within a field of view. Like the captured video with respect to camera 212, the three-dimensional depth information captured by three-dimensional camera 216 may be saved locally at memory 214. In some embodiments, remote capture device 210 may comprise a separate memory 214 for video captured by camera 212 and a separate memory 214 for three-dimensional information captured by three-dimensional camera 216. As described in greater detail below, remote capture device 210 may comprise a microphone 218 and/or at least one sensor 220 for capturing additional sensory information. Accordingly, in some embodiments, a separate and distinct memory 214 may be used for each sensory capture device (i.e., camera 212, three-dimensional camera 216, microphone 218, and/or sensor 220). In further embodiments, remote capture device 210 may comprise a single memory 214 for the storing of all captured sensory information. As described above and in further embodiments, three-dimensional information may be directly sent to computer 260 in addition to or instead of storing locally at memory 214.
In addition to capturing video and/or three-dimensional information, it may also be advantageous for remote capture device 210 to capture additional sensory information that may be presented to an operator or processed by computer 260. For example, in certain scenarios it may be advantageous for remote capture device 210 to capture audio via at least one microphone 218. Continuing with the running example, a remote assembly 202 for use with telecommunications repair may utilize audio information for diagnostic or safety purposes. For example, audio information may capture the sounds of the job site and the audio information may be processed to determine if a job site is safe. Accordingly, in some embodiments, remote capture device 210 may comprise at least one microphone 218 for the capturing of audio information. Similar to the video and three-dimensional information as described above, captured audio information may be stored locally at a memory 214 and/or transmitted to a computer 260 and/or control system 280.
Similar to audio information, remote capture device 210 may further comprise one or more sensors 220 for the capturing of additional sensory information, metrics, or data. For example, continuing with the running example, the remote capture device 210 may be used with a remote assembly 202 positioned at the end of boom assembly 114 for telecommunication or powerline work. In such a work application, the remote assembly 202 may be working on or near live powerline or other conductive lines transferring electricity. Accordingly, in some embodiments, remote capture device 210 may comprise at least one sensor 220 configured as an electricity sensor for determining whether a cable or powerline has electricity running through it. However, it will be appreciated that remote capture device 210 may comprise additional sensors 220 configured and adapted for providing remote capture device and/or remote assembly 202 with additional information. By way of non-limiting example, sensor 220 may comprise any of the following sensors: a gyroscope, an accelerometer, a thermometer, a barometer, a light emitter, a voltage meter, a current meter, among other sensors that may be utilized in the intended application of remote assembly 202.
In some embodiments, the remote assembly 202 may further comprise at least one digital Hub 220. In some embodiments, the remote assembly 202 further comprises at least one digital Hub 222. The digital Hub 22 may receive the captured sensory information from remote capture device and convert the captured sensory information into a format suitable for transmitting to computer 260 and/or control system 280. In some embodiments, the digital Hub 222 is a USB Hub, such as, for example, a USB 3.0.

As described above, motion controls 230 may be in communication with controller 224. Instructions or commands from controller 224 may be sent to motion controls 230. Upon receipt of the instructions, the corresponding controls 232, 234, 236, 238, 240, and/or 242 may be instructed to cause movement of the remote assembly 202 based on the received instructions. As described above, one or more arms or limbs of remote assembly 202 may be configured to move with 6 DOF. Based on the instructions, the corresponding motion controls 230 may cause movement of the remote assembly 202 to correspond to the instructions.
As described above, remote assembly 202 may be communicatively coupled to computer 260. In some embodiments, computer 260 may be directly coupled to remote assembly 202, such that computer 260 and remote assembly 202 are a combined system. For example, computer 260 may be directly installed into a frame or body of remote assembly 202. Accordingly, remote assembly 202 and computer 260 may be in direct communication through cables or other direct methods. In further embodiments, computer 260 may be located external to remote assembly 202. When located externally, remote assembly 202 and computer 260 may nevertheless be communicatively coupled. For example, in some embodiments, remote assembly 202 and computer 260 may be coupled through a physical connection such as an Ethernet cable or USB cable. In further embodiments, remote assembly 202 and computer 260 may be coupled through a wireless connection, such as WiFi, Bluetooth®, cellular connection, or another wireless connection. In embodiments in which computer 260 and remote assembly 202 are connected through a wireless connection, transceiver 244 may communicate with another transceiver 250 coupled or otherwise in communication with computer 260.
In some embodiments, computer 260 may receive and process sensory information captured by remote capture device 210 of remote assembly 202. Accordingly, computer 260 may comprise at least a processor 262 for executing commands, which may include instructions for processing, analyzing, or utilizing captured sensory information. For example, as described in greater detail below, computer 260 may utilize captured three-dimensional information to generate a point-cloud, three-dimensional model, or other digital representation of an object or area captured by remote capture device 210.
In some embodiments, control system 280 may be an interface, apparatus, or system providing a user with an interactive medium for interacting with computer 260 and/or remote assembly 202. For example, in some embodiments, control system 280 may comprise at least a processor 282, at least one controller 284, at least one display 288, at least one sensor 290, and at least one transceiver 292. As described in greater detail below, some embodiments of the present teachings provide for a method of controlling remote assembly 202 from a remote location. Continuing with the running example, oftentimes telecommunications repair or powerline repair sometimes occur during or immediately after a severe weather storm. This type of scenario can be wrought with dangers such as exposed and live powerlines, high winds, lightning, and other dangers that pose a risk to human workers. Accordingly, it may be advantageous for an operator of remote assembly 202 to control remote assembly 202 in a safe location, such as in a work truck or building away from the job site. Accordingly, control system 280 may comprise at least one interfacing controller 284, providing an interactive means for a user to input commands or instructions for controlling or manipulating remote assembly 202. Controller 284 may be any interface for inputting commands or instructions that can be transmitted and processed by a computer or other hardware. By way of non-limiting example, controller 284 may comprise hand-held motion control controllers. As described in greater detail below, the motion control controllers may be beneficial for an operator to perform specific movements or actions that can be captured and relayed to remote assembly 202 to perform. Through the use of motion-control controllers, an operator may be provided with a sensory effect similar to being at the job site and performing the actions themselves. However, controller 284 is not limited to motion controls and instead, controller 284 may be any interface for an operator to input instructions or commands for remote assembly 202. For example, in further embodiments, controller 284 may be a handheld controller, similar to that of a video game controller comprising thumbsticks, buttons, triggers, and/or other interfacing inputs. In further embodiments, controller 284 may comprise a joystick and button design. In even further embodiments, controller 284 may be a mouse and keyboard. In even further embodiments, controller 284 may be configured as a glove or interactive model of a hand, allowing an operator to perform native hand manipulations which may be captured and transmitted to remote assembly 202. In even further embodiments, controller 284 may comprise a camera component or other motion capture component for capturing the movement of an operator. For example, in addition to, or in place of a physical controller handled by the operator, a camera component may capture the movement of the operator. The captured movement may be transmitted to computer 260 for translation or mapping movement of remote assembly 202. Optionally, or additionally, motion capture aids, such as motion capture dots, may also be used for capturing movement of the operator. In some embodiments, may It will be appreciated that the examples provided herein are intended to be illustrative, rather than limiting, and that controller 284 may be any apparatus or method of receiving instructions or an input from an operator.
In some embodiments, control system 280 may further comprise a power medium 286 for powering one or more parts or components of control system, including for example controller 284, display 288, or the at least one sensor 290, or any combination thereof. In some embodiments, a single power medium may power all parts or components of control system 280. In further embodiments, individual parts or components of control system 280 may comprise a separate and distinct power medium 286. For example, a first power medium 286 may be used for powering controller 284 and a second power medium 286 may be used for powering display 288. Power medium 286 may be any conventionally known power source for providing power to an electrical device, including but not limited to an internal power source such as a battery, or an external battery source such as an electrical outlet.

In some embodiments, control system 280 may further comprise at least one sensor 290, which may provide additional sensory affect to the operator and/or capture additional inputs that may be used by computer 260 to provide instructions to remote assembly system 300. In some embodiments, one or more sensors may be combined with controller 284 and/or one or more sensors may be combined with display 288. For example, in some embodiments, sensor 290 may be at least one speaker or sound emitting device to provide the operator with audio information captured from remote capture device 210 or pre-recorded or pre-rendered audio. In further embodiments, the at least one sensor 290 may be one of an accelerometer, a gyroscope, a light sensor, or any other type of sensor 290 suitable to detect the viewing angle of the user or the movement, position, or angle of the operator's body.
In some embodiments, and as described in greater detail below, an operator may utilize controller 284, display 288, and the at least one sensor 290 to provide instructions to remote assembly 202, which may be analyzed and translated into instructions to cause remote assembly 202 to move or perform an action. As also described in greater detail below, an operator may input instructions or commands through control system 280. In some embodiments, inputs may be inputted or captured by a combination of controller 284 and display 288. For example, display 288 may be coupled to a head-mounted unit as described in greater detail below. An operator may move their head or torso with sensor 290 capturing the movement and/or viewing angle of the operator. The captured movement data or viewing angle may be sent to computer 260 via transceiver 292, and computer 260 may take the captured movement data or viewing angle and translate into instructions for causing remote assembly 202 to move and mimic or replicate the operator's movement and match the viewing angle of the operator.

For example, camera mount 310 may correspond to a head mount or other capture apparatus to capture the viewing angle of an operator. Instructions or commands may be relayed to robot unit 302 causing camera mount 310 to move in a corresponding manner to match the viewing angle of the operator. To enhance the operator experience, camera mount 310 may comprise a plurality of camera mount segments 312 that may be separate by motorized pivotable joints 314. The number and size of camera mount segments and pivotable joints 314 may vary depending on the embodiments and application of robot unit. Generally, in response to an instruction or commands, one or more of the pivotable joints 314 may activate to rotate or move camera mount 310. In some embodiments, the pivotable joints 314 may be used to move camera mount 310 in the X-axis, Y-axis, Z-axis as well as control the roll, pitch, and yaw of the camera mount 310.

This step may comprise robotic appendages 620 and 622 interfacing with mount 402 and actuating the mount 402 to grip said rigid object. Specifically, grabbing tool 624 or drilling tool 626 may interface with the mount to actuate the mount 402 to grip said rigid object. Step 704 may be reversed to detach mount 402 from a rigid object. The method may then continue to any step described. For example, the method may continue to step 706.
At step 706, clamp 418 is attached to an electrical cable. This step may comprise robotic appendage 620 or 622 interfacing with clamp 418 such that grabbing tool 624 or drilling tool 626 actuates clamp 418 to attach to said electrical cable. Step 706 may be reversed to remove clamp 418 from said electrical cable. The method may then continue to any step described. For example, the method may continue to step 708.
At step 708, tensioner 414 is actuated to adjust the tension of connecting line 416. This step may comprise robotic appendages 620 or 622 interfacing with tensioner 414 such that tensioner 414 adjusts the tension of connecting line 416. The step may also comprise grabbing tool 624 or drilling tool 626 interfacing with tensioner 414 such that grabbing tool 624 or drilling tool 626 actuates tensioner 414 to adjust the tension of connecting line 416. Step 708 may be reversed to adjust the tension of connecting line 416 such that any tension applied to connecting line 416 may be removed by reversing the actuation of tensioner 414. The method may then continue to any step described. For example, the method may then continue to step 710.
At step 710, tensioner 414 remains in an actuated position such that the tension of connecting line 416 does not change after connecting line 416 has been tensioned, thereby maintaining the tension in the electrical cable. Step 710 may be reversed to stop maintaining tension in the electrical cable such that wire tensioning system 400 may be uninstalled and removed from operation.
